Summary form only given. A novel scheme of laser spectroscopy is proposed and demonstrated based on a multi-wavelength dye laser array chip without wavelength scanning. An example is shown of the novel application, where the multi-wavelength output from the waveguided DFB dye laser is used which can be realized by fabricating a DFB structure with different wavelength on each waveguide. Generally the laser wavelength has to be scanned for the spectral analysis application. On the other hand, the proposed scheme with an all-solid-state polymer laser realizes a very fast and digital spectrum analysis without any spectral scan. Since the wavelengths of the waveguides can be programmed as needed, even a nonlinear spectral profile is also possible. A copolymer with rhodamine 6G was used as a core layer of the waveguide. For spectroscopy application, fifteen DFB waveguides were fabricated with a spectral pitch of 0.11 nm in the spectral region from 589.4 nm to 591.0 nm, which can cover the primary absorption D lines of sodium atom. The measurement of D lines using the multi-wavelength DFB dye laser integrated on a single chip has been demonstrated.
